Surfactant-free synthesis of monodisperse cobalt oxide nanoparticles of tunable size and oxidation state developed by factorial design

A surfactant-free synthesis of highly monodisperse Co3O4 nanoparticles via a sol-gel route was scaled-up in order to yield up to one gram of nanoparticles with a narrow size distribution. Parameters allowing for an accurate control of the crystallite size were identified and systematically evaluated...
